BOTTLE-WASHING MACHINE.

JPECIFIGATION forming part of Letters Patent No. 771,664, dated October4, 1904.

' Application filed April 17, 1902.

To all whom it may concern).-

Be it known that I, ANDERs ANDERsEN PINDSTOFTE, manufacturer, ofCopenhagen, in the Kingdom of Denmark, have invented certain new anduseful Improvements in Bottle-Washing Machines, of which the followingis a specification.

In the accompanying drawings, Figure 1 is a front elevation of a machineconstructed according to this invention Fig. 2 is a vertical sectiontaken on the line A A of Fig. 1, and Fig. 3 is a side elevation showingthe movable counterweight.

According to my invention my improved device consists of a receptacle a.fitted at its rear end with a superstructure b. In the walls of thelatter are mounted two brushes 0 and (Z, arranged one above the other,the upper brush being slightly in advance of the lower one, as shown inFig. 2. The shaft of each of the brushes is provided with a belt orstrap pulley e and f, which latter rotate the brushes in oppositedirections to each other, as indicated by the arrows in Fig. 2. In therear wall of the superstructure are provided bearings for inclinedspindles g, said spindles being arranged in such a manner that theirmedian axis is at right angles to the plane passing through the axes ofthe two brushes 0 d and cutting said plane in the center of the twoaxes. At that end of each of the spindles g situated within thesuperstructure b is mounted a brush it, while on the outside of thesuperstructure each spindle carries a belt or strap pulley 2', adaptedto impart rapid rotary motion to the spindles g, and thus also to thebrushes it. The brushes it are so arranged as to enable the distancefrom the brushes 0 and (Z to be varied. The means for driving thebrushes 0 and brushes Z2 and the direction of rotation may be variedaccording to individual requirements. The bristles of the brushes 0 andd are so cut away as to form openings 76, Fig. 1, of slightly-smallerdiameter than that of the bottles being cleaned. These openings arearranged opposite to the brushes.

Serial No. 103, L02. (No model.)

The operation of the improved device is as follows: Water is filled intothe receptacle a until the lowermost brush (Z dips therein.

'The bottles to be cleaned are inserted in the opening Zr until the.bottom touches against the brush it, (see Fig. 2,) and they are thenreleased. The brushes 0 (Z rotating press the bottles against thebrushes Z0 and at the same time clean the exterior of the bottle, whilethe brushes it clean the bottom end of the bottles and cause them toturn around between the brushes 0 (Z, so as to be cleaned all round.After the bottles have thus been cleanly brushed they are removed andreplaced by others. In the machine shown by way of example in thedrawings two bottles are simultaneously cleaned; but obviously themachine may be arranged to take any desired number.

The spindles of the brushes 0 (Z may be adjustably disposed and may, forexample, be provided with counterweights, so that the distance betweenthem is automatically regulated to suit the thickness of variousbottles.

The shaft 0 has its bearing in a lever 7', which is pivoted at 7s, saidlever having pivoted thereto a rod Z, which is connected with one arm ofthe two-armed lever m, pivoted at n. The arm of the lever or engaged bya rod Z carries a movable counterweight 0, and the other arm has pivotedthereto the rod which is connected with another single-arm lever 1' atq, said lever 1' being pivoted at s and provided with bearings for theshaft (Z. If the counterweight 0 depresses the arm m, the rod 12 willpress the lever r upward, while the rod Z depresses the lever j, whichwill cause the shafts 0 and cZ, with their brushes, to draw nearer toeach other, which is of great value if the brushes are somewhat worn outby use.

Having now described and ascertained the nature of my said invention, Ideclare that What I claim is- A bottle-cleaning machine embracing a water-receptacle, and a number or plurality of rotary brushes, upper andlower brushes thereof having their peripheries adapted to form agroove-like outline or conformation to re- In witness whereof I havehereunto set my ceive the body of the bottle, and a third brush hand inpresence of two Witnesses.
